The T-REX Trial: Tailored Regional External Beam Radiotherapy in Clinically Node-negative Breast...
Breast CancerT-REX is a randomized multicenter, non-inferiority trial. Aim: To evaluate whether regional radiotherapy may safely be omitted in clinically node negative breast cancer patients with one or two sentinel node macrometastases and an estrogen receptor positive, HER2-negative tumor. Leading to an improved quality of life and reduced side effects, without worsening recurrence free survival at five years. Intervention: Patients will be randomized to locoregional radiotherapy towards the breast/chestwall and regional lymph nodes vs. to a de-escalated radiotherapy. In the intervention arm no lymph node irradiation will be given. Radiotherapy is still given to the remaining breast after breast conserving surgery, but no radiotherapy is given after mastectomy. Sample size: 1350 patients Primary end-point: Recurrence free survival at five years. Gene expression analysis: For all patients gene expression analysis for the gene signatures ARTIC, POLAR and OncotypeDX will be performed in collaboration with Exact Sciences, and related to risk of recurrence and benefit of adjuvant radiotherapy.

Triple Negative Breast CancerThe objective of this study is to evaluate the efficacy and safety of a new treatment regimen (Chidamide combined with Zimberelimab) in the treatment of patients with metastatic triple negative breast cancer after the second-line therapy.
To Evaluate a Phase Ia/Ib Clinical Study of EG017 in Patients With Advanced Breast Cancer.
Breast CancerTo evaluate the safety, tolerability, pharmacokinetics and efficacy of EG017 in androgen receptor-positive, estrogen receptor-positive, and human epidermal growth factor receptor-2-negative patients with advanced breast cancer.
Single-dose Preoperative Partial Breast Irradiation in Low-risk Breast Cancer Patients
Breast CancerIn this ABLATIVE-2 trial, low-risk breast cancer patients will be treated with MRI-guided single dose preoperative partial breast radiotherapy to assess the rate of pathologic complete response after an interval of six to twelve months between radiotherapy and surgery. Response monitoring will be assessed using MRI and markers in blood and tumor tissue to enable prediction of pathologic response.
Pyrotinib Rechallenge in Her2-positive Metastatic Breast Cancer Pretreated With Pyrotinib and Trastuzumab...
HER2-positive Breast CancerMetastatic Breast CancerPyrotinib is an oral tyrosine kinase inhibitor targeting both HER-1 and HER-2 receptors. This study is a randomized, open-label, multi-center, parallel design study of the combination of pyrotinib, trastuzumab and chemotherapy versus trastuzumab and chemotherapy in HER2+ MBC patients, who have prior received trastuzumab and pyrotinib. Patients will be randomized in a 2:1 ratio to one of the following treatment arms. Arm A: pyrotinib + trastuzumab + chemotherapy, Arm B: trastuzumab + chemotherapy. Patients will receive either arm of therapy until disease progression, unacceptable toxicity, or withdrawal of consent.

Genomics Guided Targeted Post-neoadjuvant Therapy in Patients With Early Breast Cancer (COGNITION-GUIDE)...
Early-stage Breast CancerIn early breast cancer (eBC), pathological complete response (pCR) after neoadjuvant therapy acts as surrogate marker for metastasis and overall survival. Therapy intensification by adding an adjuvant therapy line (post-neoadjuvant treatment) substantially lowers the risk of relapse in high-risk breast cancer patients with residual disease after neoadjuvant treatment (non-pCR). While this approach was exemplified in two phase III trials without biomarker-stratification (CREATE-X, KATHERINE), even higher efficiency might be achieved by individualized genomic-guided post-neoadjuvant therapies. Within the seven-arm umbrella phase-II clinical trial COGNITION-GUIDE, we aim to deliver molecularly-tailored cancer care by implementing an additional response- and genomics-guided post-neoadjuvant therapy after finishing the guideline-compliant post-neoadjuvant treatment in high-risk breast cancer patients with residual cancer burden after neoadjuvant therapy to reduce the substantial risk of local and distant relapse. The trial evaluates not a single drug but rather a general strategy of precision oncology in the curative setting and provides the basis for future confirmatory biomarker-driven trials. Allocation to the therapy-arms is conducted by in depth molecular characterization of tumors within the COGNITION registry program. The study aims to show an overall benefit of the precision medicine approach in high-risk eBC patients and to allow for secondary exploratory evaluation of each study-arm. The primary endpoint of the study is invasive Disease-Free Survival (IDFS) after 4 years measured from surgery to local or distant relapse or death. The sample size of the entire trial is 240 eligible patients.
